The concept of "fair play" in sports is hardly a new one. Students need to learn that a clean body check in hockey for instance is fair. As is a fight between two or more players who have consented with each other that they want to fight on the ice. But what's unacceptable is hits with intents to injure. Hits like the ones placed on Edmonton Oilers player Sam Gagne who had his jaw broken & his teammate Taylor Hall who took a serious head shot against the Vancouver Canucks in a pre-season match the other night.
